Kua tāruatia ki te papatopenga
1.2\times \frac{5}{3}-\left(-\frac{1\times 10+7}{10}\right)
Whakawehe 1.2 ki te \frac{3}{5} mā te whakarea 1.2 ki te tau huripoki o \frac{3}{5}.
\frac{6}{5}\times \frac{5}{3}-\left(-\frac{1\times 10+7}{10}\right)
Me tahuri ki tau ā-ira 1.2 ki te hautau \frac{12}{10}. Whakahekea te hautanga \frac{12}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
\frac{6\times 5}{5\times 3}-\left(-\frac{1\times 10+7}{10}\right)
Me whakarea te \frac{6}{5} ki te \frac{5}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
\frac{6}{3}-\left(-\frac{1\times 10+7}{10}\right)
Me whakakore tahi te 5 i te taurunga me te tauraro.
2-\left(-\frac{1\times 10+7}{10}\right)
Whakawehea te 6 ki te 3, kia riro ko 2.
2-\left(-\frac{10+7}{10}\right)
Whakareatia te 1 ki te 10, ka 10.
2-\left(-\frac{17}{10}\right)
Tāpirihia te 10 ki te 7, ka 17.
2+\frac{17}{10}
Ko te tauaro o -\frac{17}{10} ko \frac{17}{10}.
\frac{20}{10}+\frac{17}{10}
Me tahuri te 2 ki te hautau \frac{20}{10}.
\frac{20+17}{10}
Tā te mea he rite te tauraro o \frac{20}{10} me \frac{17}{10}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{37}{10}
Tāpirihia te 20 ki te 17, ka 37.
